HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 81809 i.e. 91 the largest integer that leaves a remainder zero for all numbers.
HCF of 546, 81809 is 91 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 546, 81809 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 546, 81809 is 91.
HCF(546, 81809) = 91
HCF of 546, 81809 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 546, 81809 is 91.
Highest Common Factor of 546,81809 is 91
Step 1: Since 81809 > 546, we apply the division lemma to 81809 and 546, to get
81809 = 546 x 149 + 455
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 455 and 546, to get
546 = 455 x 1 + 91
Step 3: We consider the new divisor 455 and the new remainder 91, and apply the division lemma to get
455 = 91 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 91, the HCF of 546 and 81809 is 91
Notice that 91 = HCF(455,91) = HCF(546,455) = HCF(81809,546) .
